TEHRAN (FNA)- Findings of a recent study showed that ginkgo biloba is not efficient enough to keep cognitive decline and the resulting Alzheimer's disease at bay.
Previous studies had found the medicinal herb to be an effective memory- and cognition-enhancing product.
According to the study published in the Journal of the American Medical Association, ginkgo does not slow down the progression course of dementia in individuals suffering from mild cognitive impairment.
Findings even revealed a slightly higher risk of dementia and Alzheimer's disease in individuals taking this herbal product; the difference, however, was not statistically significant.
The study pointed out an increased risk of hemorrhagic stroke following the use of gingko in individuals with a positive history of cardiovascular disease and those taking the blood thinner drug.
Scientists concluded that gingko biloba extract does not prevent dementia in individuals with or without cognitive impairment, and is therefore ineffective in tackling Alzheimer's disease.
